すのである。 Conventional voice coils for speakers of this type include those shown in FIGS. 1 and 2. This speaker voice coil is created by the following steps. First, wind a rectangular bobbin base paper A around a coil jig, butt both ends B 1 and B 2 together, and attach the bobbin C.
form. Next, the coil D is wound onto the bobbin C using a winding machine. Finally, add the banding paper E to the coil D.
Wrap it around bobbin C at the top of
The lead wire F of the coil D is pulled out from between the and the band E.

ならないという欠点があつた。 Conventional voice coils are constructed as described above, so if a strong material is used as the bobbin C material, or if the bobbin C is
If the vertical width of the bobbin C is quite large, the portion of the coil D on the bobbin C will be a perfect circle, but the upper end portion of the bobbin C will not be a perfect circle and will be deformed. especially,
The part of the seam of the bobbin C that is not covered by the band paper E protrudes at an obtuse angle. Therefore, when assembling a speaker using this voice coil,
The protruding part of the bobbin C cannot be inserted into the gap of the magnetic circuit. Therefore, in order to suppress this protruding part, it was necessary to attach a reinforcing band to the upper end of the seam, or to make the bobbin base paper A curl in the front. .

FIG. 3 is a perspective view of the voice coil according to the present invention, and FIG. 4 is a plan view showing the constituent parts of the voice coil. In the drawings, reference numeral 1 denotes a rectangular bobbin base paper, and corner portions 3a and 3b at both ends 2a and 2b of line-symmetrical positions are cut off at small angles. Next, a process for assembling a speaker voice coil using the bobbin base paper 1 described above will be explained. First, the bobbin base paper 1 is wound around a coil jig and both ends 2a and 2b are butted together to form the bobbin 4. At this time, the upper end of the abutted portion of both ends 2a, 2b is cut by corner portions 3a, 3b.
A V-shaped recess 5 is formed. Next, the coil 6 is wound onto the bobbin 4 using a winding machine. Then, the band 7 is wound around the upper half of the bobbin 4, which is the upper part of the coil 6. At this time, the upper end of the band 7 is close to the upper end of the bobbin 4 and is wrapped so as to cover the upper end of the V-shaped recess 5 of the bobbin 4. Note that the lead wire 8 of the coil 6 is
It is pulled out from between the band 7 and the bobbin 4.

リード線８を引き出すようにしたものである。 As described above, the present invention includes a cylindrical bobbin 4 having a V-shaped recess 5 formed by the corner cutouts 3a and 3b provided in the bobbin base paper 1, and the bobbin 4.
The coil 6 is wound around the outer periphery of the lower half of the bobbin, and the coil 6 is wrapped around the outer periphery of the upper half of the bobbin so as to cover the upper end of the V-shaped recess 5 up to the vicinity of the upper end of the bobbin 4. A wide band 7 is formed, and the lead wire 8 of the coil 6 is drawn out from between the bobbin 4 and the band 7.
